What’s the answer this is hard

Mathematics
1 answer:
Vanyuwa [196]4 years ago

Answer:

Lowest point y = -2, highest point = 6

Step-by-step explanation:

The given function is g(t) = 4sin (3t) + 2

When we plot the function on a graph we use the sine graph y = a sin(bx+c) + d. Here a is amplitude, c is horizontal shift and d is vertical shift.

Therefore in this function d is 2 so sine graph is vertically shifted of we can say y = 2 is the center line  

Here in the given function amplitude of the sine wave is 4.

The lowest point on the graph will be y = 2-4 = -2

The highest point of the graph will be y = 2+4 = 6

On a December day, the probability of snow is 0.30. The probability of a "cold" day is 0.50. The probability of snow and "cold"
Margarita [4]

Answer:

Yes, snow and cold weather are independent.

Step-by-step explanation:

We are given the following in the question:

C: Cold weather

S: Snow

P(C) = 0.50

P(S) =0.30

P(S\cap C) = 0.15

We have to check whether snow and cold whether are independent events.

If the events A and B are independent then,

p(A\cap B) = P(A)\times P(B)

Checking,

p(S\cap C) = P(S)\times P(C)\\0.15 = 0.30\times 0.50

Thus, the two events are independent.

For mutually exclusive events

P(A\cap B) = 0

Thus, the given events are not mutually exclusive.
